Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles

Polymer Engineering &Science, EarlyView.
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.

Correlation Between Strain Gradient and Fracture Damage Mechanism of TA18 Alloy Based on In Situ SEM/EBSD Analysis

Rare Metals, EarlyView.
ABSTRACT TA18 alloy is an ideal material for piping systems in the aerospace field, the low notch sensitivity and high damage tolerance enhance its engineering application value. However, the complex failure mechanism influenced by strain gradient necessitates further improvement of the service stability for TA18 alloy in practical engineering ...

Dynamic Phase Transformation Mechanisms in Ti48Al5Nb2Cr0.6Re0.1C Alloy With Heterogeneous Layered Microstructure

Rare Metals, EarlyView.
ABSTRACT Introducing solid‐state phase transformations into the design of heterogeneous structures is considered an effective strategy for simultaneously optimizing both microstructure and mechanical properties. This study investigates the thermodynamic and kinetic mechanisms of the γ → α transformation in Ti48Al5Nb2Cr0.6Re0.1C alloy under different ...
